Answer: 89
Step-by-step explanation: First find the mean add all the numbers up and divide by the amount of numbers. 641/7 is 91.57. She needs at least atleast a 89.
Answer: C. 13 + 8x = 45
Step-by-step explanation:
She already has 13 dollars. This would be the b-value in the equation, thus eliminating options A and B because those two feature 13 as the m value.
She earns $8 per hour. Let x = number of hours walking dogs.
Since 8 is the slope, it would be attached to x, thus either C or D would be the correct response
Since Grace is adding 8 dollars per hour, not subtracting, D is incorrect, leaving C to be the correct answer.

The answer is

Step-by-step explanation:
First you have to find the radius of sphere by dividing diameter by 2 :

Let diameter = 14,


Next you have to use the volume of sphere formula :

Let r = 7,



(5*3)(2*3)=(15)(6)=90
7*3=21
21*3=63
Answer:
The slope is 2
